A novel compact rectifier for dual-band operation in the RF energy harvesting is presented. The circuit comprises a 4th order dual-band impedance matching and a single-series circuit with one double diode, both are integrating into a compact shape to occupy a small area of 30 × 35 mm. The merit of the proposed rectifier circuit is that it can be extended to n number of the frequency band by usi...

In this paper, a novel autotransformer for 28-pulse AC-DC converter configuration is designed, modeled and simulated to feed vector controlled induction motor drive (VCIMD). The proposed autotransformer configuration consists of two paralleled 7-pulse AC-DC converters involving seven-phase shifted uncontrolled diode bridges with pulse doubling circuit. It improves power quality at AC mains and ...

Properties of the 5-hydroxytryptamine (5-HT)-induced current (I(5-HT)) were examined in neurons of rat dorsolateral septal nucleus (DLSN) by using whole cell patch-clamp techniques. I(5-HT) was associated with an increase in the membrane conductance of DLSN neurons. The reversal potential of I(5-HT) was -93 +/- 6 (SE) mV (n = 7) in the artificial cerebrospinal fluid (ACSF) and was changed by 54...

The delayed rectifier K+ current in Drosophila is similar to the classical delayed rectifier, originally described by Hodgkin and Huxley. Drosophila provides unique tools of mutant analysis to unambiguously determine the genetic identity of this native K+ current. We identified the Shab gene as the exclusive gene underlying delayed rectifier currents in both muscle and neurons. In muscles, a ge...

PURPOSE This study examined the expression and function of inward rectifier K(+) channels in cultured rat hepatic stellate cells (HSC). MATERIALS AND METHODS The expression of inward rectifier K(+) channels was measured using real-time RT-PCR, and electrophysiological properties were determined using the gramicidin-perforated patch-clamp technique. RESULTS The dominant inward rectifier K(+)...

Class III antiarrhythmic drugs show promise as effective treatments for the suppression of potentially lethal cardiac arrhythmias. Dofetilide (UK-68,798), is a potent class III antiarrhythmic agent that is presently under clinical investigation. The objective of this study was to determine whether [3H]dofetilide could be used as a specific radioligand for the rapidly activating delayed rectifie...

Convolutional rectifier networks, i.e. convolutional neural networks with rectified linear activation and max or average pooling, are the cornerstone of modern deep learning. However, despite their wide use and success, our theoretical understanding of the expressive properties that drive these networks is partial at best. On other hand, we have a much firmer grasp of these issues in the world ...

Present day IGBT based power adjustable speed drives have fast turn-ON and turn-OFF times results in high dv/dt being applied to the motor terminals. The high dv/dt switching waveforms along with travelling wave effects of long cables stress motor insulation, cause high ground currents and affects the motor bearings. These issues are exacerbated in PWM Active Front End (AFE) rectifier based mot...

Three kinds of redox-mediated behavior were realized at an azobenzene-functionalized electrode, which has great potential for application in the field of molecular devices. According to these results, the functionalized electrode could act as either a cathodic molecular rectifier or anodic molecular rectifier.

BACKGROUND During spinal and epidural anesthesia with opioids, droperidol is added to prevent nausea and vomiting. The mechanisms of its action on spinal sensory neurons are not well understood. It was previously shown that droperidol selectively blocks a fast component of the Na+ current. The authors studied the action of droperidol on voltage-gated K+ channels and its effect on membrane excit...
